EMLINK

A file systemerrno, "Too many links": this error reports that a link(2) operation would result in the target file having too many links, greater than the pre-defined constant "LINK_MAX" (which is usually 32767). This applies firstly to the user-executed link(2) call, but it also applies directory creation. The upshot of this is that you may not have over 32765 subdirectories in one directory, but this would be stupidly expensive to do in the first place, and completely impractical.
